Abstract A variety of 3-arylated di-and tetrahydro-2 H-2-benzazepin-1-ones were efficiently assembled through a sequence involving a Suzuki–Miyaura cross-coupling reaction with enol phosphates derived from the corresponding benzazepine-1, 3-diones. This technique has been further exploited for the construction of the homoprotoberberine skeleton, which was readily accessed by intramolecular carbocationic annulation reaction applied to a ...
